Betting maths on the numbers you enter. Amounts are in pounds (£).
Everything is worked out in your browser. Nothing you type is sent or saved.
Type a price in the format chosen above and see it in all three. Decimal odds include the stake (2.50 returns £2.50 per £1); fractional shows the profit per stake (3/2); American shows the profit on £100 (+150), or the stake needed to win £100 when it starts with a minus (−200).
Fractional results use the nearest traditional price; a ~ means it isn't exact.
Results are a record of maths on the numbers you enter, not advice.
